BEIJING, Dec. 3 (Xinhua) -- Chinese astronauts may get fresh vegetables and oxygen supplies by gardening in extraterrestrial bases in the future, an official said after a just-concluded lab experiment in Beijing.

Deng Yibing, deputy director of the Beijing-based Chinese Astronaut Research and Training Center, said that the experiment focused on a dynamic balanced mechanism of oxygen, carbon dioxide, and water between people and plants in a closed system.
